GPS sounds = expensive. And many times i'm on relatively slow tracks where speed below 60 is not that rare. There are road portions with 70kmh max in city too. And there is sometimes wish for some Loud elsewhere from get go. I'd love to get reasonably priced exhaust with prefitted valve though to skip welding / modifying mufflers / adding extra pipes to exhaust not designed for such though, but if it will cost what i predict it will, i'm not that rich
